DC68030	C6mPhE-383	C6mPhE-383 is a top-performing ionizable lipid featuring an aromatic ring and a bioreducible disulfide bond. Formulated into lipid nanoparticles, it preferentially delivers mRNA to lymphoid tissues (lymph nodes/spleen) while minimizing off-target liver accumulation after intramuscular injection. In a SARS-CoV-2 vaccine study, it elicited strong antibody responses, promoted protective effector memory T cells, and exhibited enhanced safety by significantly reducing systemic inflammatory cytokines compared to the standard SM-102 LNP.
DC67650	EB-Lipid	EB-Lipid is an innovatively engineered ionizable lipid designed to replace conventional PEG-lipid in mRNA vaccine formulations. Its structure comprises three key components: an Evans Blue-derived headgroup with high affinity for albumin, a tetraethylene glycol linker that enhances colloidal stability, and dual oleate tails for anchoring into lipid bilayers. This molecular design enables EB-Lipid to actively recruit endogenous albumin, forming an albumin-rich protein corona on the surface of lipid nanoparticles (LNPs). Following intramuscular administration, these albumin-bound EB-LNPs are preferentially transported through lymphatic vessels rather than entering the bloodstream, thereby avoiding hepatic accumulation and associated hepatotoxicity risks.Experimental data demonstrate that EB-LNPs achieve significantly higher accumulation in lymph nodes, where they are efficiently internalized by dendritic cells via albumin receptor-mediated endocytosis (e.g., gp60). This process enhances antigen presentation and activates robust cellular and humoral immune responses. In both tumor models (B16-OVA and HPV-associated) and infectious disease models (H1N1 and SARS-CoV-2 Omicron), EB-LNP-based mRNA vaccines elicited potent cytotoxic T-cell activation and durable neutralizing antibody production at low doses. Unlike traditional PEG-LNPs, EB-LNPs show minimal liver distribution, reduced immunogenicity, and improved safety profiles after repeated administrations.By leveraging albumin’s natural trafficking pathway, EB-Lipid represents a transformative delivery platform that combines targeted lymph node delivery with enhanced biosafety, positioning it as a promising candidate for next-generation mRNA vaccines and therapeutics.
DC60843	CF3-2N6-UC18	CF3-2N6-UC18 is a rationally designed chloroquine-inspired ionizable lipid that enables robust mRNA delivery and genome editing. It integrates three modular components: a 7-trifluoromethyl-substituted quinoline scaffold (mimicking chloroquine’s endosomolytic properties), a hexamethylenediamine linker with two ionizable nitrogen atoms (pH-responsive protonation), and two unsaturated oleyl (C18:1) hydrophobic tails (enhancing membrane fusion and nanoparticle stability). This lipid self-assembles into ecoLNPs (endosomolytic chloroquine-like lipid nanoparticles) with spherical morphology (~200 nm diameter, 98% mRNA encapsulation). Its pH-sensitive activity triggers endosomal escape through dual mechanisms: proton sponge effect (buffering endo-lysosomal pH) and saposin B-mediated membrane disruption (molecular docking confirms chloroquine-like binding to lysosomal saposin B). In vitro, ecoLNPs outperform commercial reagents (18.9-fold higher mRNA delivery than Lipofectamine 2000) and penetrate 3D cell models. They resist serum/RNase degradation and retain >90% activity after 7-day storage at 4°C. In vivo, ecoLNPs achieve tissue-specific mRNA expression via multiple routes (intravenous, intramuscular, etc.), with strong lymph node tropism (90.2% after intramuscular injection) comparable to SM-102 LNPs (Moderna’s COVID-19 vaccine carrier). They mediate efficient Cre mRNA-driven recombination and CRISPR-Cas9 editing in transgenic mice. CF3-2N6-UC18’s modular design, stability, and dual endosomal escape strategies position it as a versatile platform for mRNA vaccines, gene therapy, and genome editing applications.
DC85555	YK-009	YK-009 is an advanced, biodegradable ionizable lipid designed for efficient mRNA delivery. Via intramuscular injection, it demonstrates superior targeting to draining lymph nodes, boosting immune cell transfection for vaccines. When administered intravenously, it distributes to the liver but leverages a highly degradable chemical backbone to ensure rapid clearance post-endosomal escape. This effectively eliminates the risk of long-term tissue accumulation and liver toxicity seen in traditional lipids. Delivering a balance of high transfection efficiency and exceptional biocompatibility, YK-009 is an ideal component for safe and potent lipid nanoparticle (LNP) formulations.
